ANTOINE ARCHAMBAULT, OF NORTHAMPTON, MASSACHUSETTS.

WIN DOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 408,786,dated August13, 1889.

Application filed April 3, 1889. Serial No. 305,843- (No model.)

To all whom, it may concern:

Be it known that I, ANTOINE ARCHAMBAULT, a subject of the Queen of GreatBritain, resid' ing at Northampton, in the county of Hampshire, andState of Massachusetts, have invented new and useful Improvements inWVin- (low-Screens, of which the following is a specification.

This invention relates to rolling windowscreens, or to that classadapted to be by one end affixed to the sash and to be drawn up by andwith the sash when the window is opened, thereby screening; the windowopening to whatever extent of opening there may be, whether more orless, and to be withdrawn and disposed 011 a spring-reacting roller asthe sash is lowered and the window-opening closed; and the inventionconsists in the construction and combination of the various parts, allsubstantially as will be hereinafter fully described, and specificallyset forth in the claim.

In the accompanying drawings, Figure 1 is a front elevation of a windowframe or casement and the screen mechanism of this invention appliedthereto, with parts broken away for clearer illustration; and Fig. 2 isa vertical cross-sectional view of the same on line 00 00, Fig. 1.

In the drawings similar letters of reference indicate correspondingparts in all the Views, and A represents the window-casement, the uppersash B sliding in the ways I) therefor, and the lower sash C sliding inits ways 0, and under or within the Window-sill a ahorizontally-extending chamber D is formed, in which is mounted aspring-reacting roller or reel E, on the periphery of which one end ofthe screen F of textile netting or wire-gauze, is secured, which screenis of a width substantially equal to the width of the window. The upperend of said screen is provided with a horizontal rigid strip or bar G,to which it is attached.

' The upper wall of the window-sill casing- I chamber, in and about theplane of the sash,

is formed with an opening d of sufficient width to permit the freepassage therethrough of the screen, and the upper orifice of saidopening is forwardly extended, as at f, form ing a ledge g, on which theflange h of the strip G may rest, the main vertical portion of saidstrip being adapted to lie within the said opening cl, and at the timethe sash is raised and the said strip not connected thereto the saidflange of the strip will close the opening, being prevented fromfollowing the screen through said opening by the flange and ledgeengagement, and itwill be seen by the formation of the said opening (1with the laterallyextended orifice, and of the strip G with the flange,that when the said strip is in its lowermost position and resting by itsflange on the ledge the 'top of the strip may lie flush with the uppersurface of the window-sill, and therefore the said strip constitutes noimpediment to the close contacting of the sash with the window-sill andthe complete closing of the window; and, moreover, when not desired tohave the screen raised with and by the window-sash, as is sometimesdesirable while the window is raised, exposing the top of thewindow-sill, no aperture is left uncovered for the entrance of dust ormoisture to the interior of the screen-inclosing casing, the rest of thesaid flange on the ledge forming an effectual dust-guard. In accordancewith this invention the said strip G is adapted to be connected to thelower edge of the sash by a catch device which is capable of easyattachment and detachment, the construction and arrangement of which,fully shown in the drawings, is as follows:

The lower rail of the sash is recessed between its sides, as at 2', saidrecess being open atthe lower edge of the sash, and in said recess is atransverse spindle j, bearing for rotation in the sashrail, whichspindle has at its end projecting beyond the outside of the sash-rail ahandle-knob 70, by which to conveniently turn it, and said spindle isalso provided with a hooked arm Z, fixed thereto and movable to swingwith the spindle within the said recess.

m represents an angular arm on the upper edge of the strip G, adapted,when the hooked arm Z is properly swung into the upper part of therecess and the strip and sash rail brought to contact, to protrude intothe recess, and then on swinging the hooked arml by turning the knob toengage the angular arm m the strip will be connected to move with thesash.

The mounting of the spring reacting roller E for the screen within thechamber D of the easement is accomplished by supporting a shaft IIimmovably in the chamber D, on which the c \;'lindrical roller isaxially and loosely mounted, a coiled spring 1) comprisin g amultiplicity of couvolutions being wound about said shaft, one end ofwhich is fixed to the shaft, as at q, while the other end thereof isattached to the head of theroller, as shown at r.

\Vith the screen-strip G through the catch devices above describedconnected to the sash, on raising the latter the screen will be unwoundfrom its roller, and on lowering the sash the roller will turn under therecoil of its spring and the screen will be correspondingly rewoun d.

WhatI claim as my invention is- The combination, with a windou illhavinga easing thereunder and an opening r] therethrough, and the sashhaving in its lower rail a recess 1' within the thickness thereof andextended upwardly vertically from the lower edge thereof, the horizontalrotatable spindle projected across said recess and pro vided thereinwith the hooked arm Z, said spindle being extended through and beyondthe outer side of the sash-rail and there provided with a handle-knob,of the spring-reactin g roller, and the flexible screen thereon pro-,iected through said casing-opening, and provided with the strip G,having the angular arm m adapted to project into said sash-recess i andbe engaged by said hooked spindlearm I, all substantially as shown, forthe purpose set forth.
